Howdy, Drove the car over the weekend, in torrential rain. Wife alerted me to water gushing in from the back of the glovebox - instantly knew what what it was. So checked the drain hole and it was blocked, cleaned it out and water dumped out the valve as it should. Currently have the carpet, filters, glove box and the bottom of the blower motor off drying out. The blower motor still works, but I get no air out of the vents. Anyone know the reset procedure for an '02 W220? Ta.
